Cremaster: Ferran Fages - feedback mixing board, electro-acoustic devices / Alfredo Costa Monteiro - objects on electric guitar, electro-acoustic devices & Sophie Agnel: piano. Recorded separately in Barcelona and Montreuil between 2009 and 2011. Final assemblage in March 2012. Mastered by Ferran Fages. Between 2010 and 2012 Cremaster started a series of collaborations with Sophie Agnel and Angharad Davies. After more than 10 years dealing with electro-acoustic devices they wanted to go further, exploring the timbrical possibilities of their electronics with an acoustic instrument. For this new challenge they chose Angharad Davies' violin and Sophie Agnel's piano. Isotopic is the second in the series of these recorded collaborations, the piano sounds having first been recorded by Sophie Agnel and then mixed by Cremaster with their own sounds. The first document of this period of experimentation was "Pluie fine" with Angharad Davies on French label Potlatch in 2012. The purpose of working with Sophie Agnel was not only to open the range of possibilities timbrically for the duo, but also to collaborate with a musician who works in a similar direction, in an almost physical relation with the instrument.
